Wahl 9655

Cheap, lots of attachments, and does a good job of cutting hair so far

When we unplug ours, it slows way down unless you press down on the On/Off switch. I'm not sure why that is. Once I hold the switch down, or plug it back in, it goes back to normal speed. I need to get around to calling the company to inquire about...

None

Battery only lasted about 3 minutes (after charging it for several hours), had to plug it in to finish cutting my hair, motor very weak

Cordless feature is a big advantage. It cuts very well with the included attachments

This unit does not edge trim well at all, something our old corded model had no trouble with
